    Math.min.length is 2, which weakly signals that it’s designed to handle at least two parameters

    Why would they even define this value?

    Note: I’m not a js dev, do most functions have length?

        Most people don’t use JS because they think it’s perfect… they use it because it’s the language that works on web browsers… or because thier coworkers made something in it… or because the library that does what they want uses it…

      All functions built with function name(args) { body } syntax have a length based on the form of args. Other ways to create functions might set length (I’m not sure). Most of the functions provided by the runtime environment do have a length, usually based on the number of “required” arguments.
